USES OF PHOTOGRAMMETRY.
Photogrammetry can be used for the following purposes.
(1) Preparation of image maps useful for many reconnaissance and planning purposes. Such image maps include digital mosaics (unrectified, rectified, controlled, uncontrolled)..
(2) Compilation of planimetric and topographical maps and plans of large areas.
(3) Preparation of route maps for roads, power-lines, pipelines, canals for storm waters drainage.
(4) Computation of positions, distances, areas of geometric objects, volumes.
(5) Generation of DTM (DEM) and perspectives (drapped maps)
(6) Production of orthophoto map
(7) Mapping of inaccessible areas
(8) Freezing of a rapidly changing phenomenon for study
(9) Documentation of Archeological monuments.
Photogrammetry is rapid and economical for the survey of large areas than any other method.
